PROBLEM TO BE SOLVED: To provide a gas-insulated switchgear in which dielectric breakdown can be prevented while down-sizing.SOLUTION: A gas-insulated switchgear includes a plurality of ground tanks 2 interconnected by a connection flange 20, and filled with insulation gas 6, a high-voltage conductor 1 installed in the ground tank 2, a sector insulator 10 as a support insulator insulation supporting the high-voltage conductor 1 for the ground tank 2. A tank side fixing member 9 is inserted unto a through hole 13 formed in the connection flange 20 toward the ground tank 2, and fixes the tank side end of the sector insulator 10, as a support insulator, to the ground tank 2. |
